Question

Effects of heat We cannot measure heat directly, but we can detect its effects on an object. Changes in heat energy can be seen as change in temperature change in size (thermal expansion de change of state Change in temperature When heat is supplied to an object, there is usually a rise in the temperature of the object. Similarly, when an object is cooled, its temperature usually decreases. Thus, the amount of heat gained or lost by an object can usually be found by measuring the change in the temperature of the object.

Answer:

Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions.
